nature of a childs gun or toy gun, which is of the repeating type. Q

he air `gun of the present invention is one which embodies improvements over the one shown in the patent application of Victor H. Forsman, Arnold J. Decker, and Arthur Edwards, Serial No. 324,880, and filed December 10, 1928. The present invention embodies a mechanism for effecting the repeating action of the gun substantially as shown in this said application, but in conjunctionV with the mechanism there are a number of improvements both in details of the mechanism itself and in a safety apparatus which is effective during the cooking of the gun. The safety apparatus is such as to insure that the cooking action and the feedingof a pellet from the magazine, both occur in a given .cooking movement; in other-words, the safety is provided so that it is not possible to perform either the feeding of the pellet or the cooking of the gun without effecting the other action. arranged to prevent accidental firing of the gun until the cocking action is entirely completed.

Fig 11 is a detailed view illustrating the trigger and sear. y The gun comprises essentially the' usual barrel 1, stock 2, trigger, and pump handle 4. The pump handle may be carried by a sheet metal frame construction 5, generally U-shaped in cross section, as illustrated in Fig. 5, and which engages the sides of the gunbarrel and gun vframe 6 in a manner to guide the handle 4 as vit is reciprocated for cooking purposes.

The interior of the gun includes a mechanism which comprises a spring pressed plunger in the barrel which may be ofany Such a plunger is shown at 10, mounted upon a rodll and the spring is shown at 12. Thel plunger is disposed withinl a barrel 13, disposed with the barrel 1, and in this regard,`the barrel 1 is in effect aVV false barrel. The rod 11 has a hooked end '12a which is arranged to be caught behind a Sear '14 on the trigger. The

`trigger-being held normally with the Sear urged upwardly by a suitable spring 15. Both the false barrel and the inner air barrel are slotted, as shown in Fig. 5; and attached to the rod 11 isa depending member 16 which projects through the slotted barrels and which is connected to the pump handle 4.

VThis may be accomplished by turning over the ends 17 of the metal member 16 so as to jin effect, rivetthe pump handle 4 to the part 16.9 `Therod'll is provided 'with 'an enlargement 18, forward Vof which is a sleeve 19 which spaces the enlargement 18 in the member 16. Accordingly, as will be noted by reference to Figs. 2, 3 and 4, a backward pull on the handle 4 retracts the rod 11 until it is hooked behind the sear .14 of the trigger where it is held in its position. Vhen the trigger is pulled in the usual manner, the rod is released and the plunger moves forwardly in the barrel 13 under the action of spring 12. The pellet to be ejected when the gun is shot is of course, disposed in the end of the barrel 13, and the gun includes a magazine from which a pellet is fed in each cooking movement and placed in this position. The magazine is shown at 2O and it is provided with a spring-pressed follower 21,. in the nature of a cylinder with a crossed end 22 and a projecting handle 23` The pellets are shown at 24. To place the pellets in the magazine, the handle 23 isv retracted beyond the opening 25 and then a plurality of pellets are dropped in the magazine 20; and upon release of handle 23, they are urged forwardly by spring 26. The forwardmost pellet, however, is stopped becauseE it butts against the end of a combined stop yand feed `member 30. This member is shown in Fig. 10, and is advantageously composed of sheet metal bent generally into U-shape in cross section, provided with elongated apertures 32 and ears 33. The forward portion of the `magazine is vcut away, or slotted as at 34, and the stop member is mounted in place by means of a fulcrum pin 35 extending through the elongated slots. A suitable spring 36 is placed around the pin, preferably-within the member 30, one end of which engages an abutment 37 and the other of which engages the inner' wall of the bight portion ofthe member 30. This spring holds the member 30 normally in position,- shown in the full lines of Fig. 1, with ears 33 abutting against the outside of the magazine .and with the opposite end of the member 30'being urged upwardly so that the bottom ofthe elongated slots stop against the fulcrum pin 35. ln this position, the forwardm-ost ball, or pellet in the magazine strikes against the stop member. 'There is a slotted stop member which 'is fixed in position, as illustrated at 40, the purpose of which will presently appear.

This combined stop and feed ,member 30 is actuated when the gun is cocked to allow the forwardmost pellet to be forced out of the magazine by the spring 26 and then to feed this pellet .upwardly into "an approximate alignment-with the barrel 13'so that it may be placedin the barrel. For accomplishing this, a gun is provided with-a slot 40, having a lower substantially horizont-al portion and upward substantially horizontal portion and intermediate inclined portion. There is a U-shaped wire-like member 41 having its ends connected, as at 42 to oppostesides of .the Aslide member 5, with 'its legs extending :forwardly and with its bight vposed in the slot 40.y

portion diseventually, where it engagesl the said pellet and force- -atively long strip This construction functions to feed a pellet from the magazine into the barrel 13 as follows: Upon retracting the member 4, the wire member 41 is also retracted, and the bight portion 43 strikes the end of the member 30 above the fulcrum pin 35; continued movement causes the bight portion to rock the member 30 to the position shown substantially by the dotted lines (Fig. 1). The forwardmost pellet now is moved forward owing to the action of spring 26 until it strikes the abutment 30; further continued retracting movement of the handle 4 causes the bight portion 43 of the wire to move past the engaged end of member 30, whereupon the spring;.36v snaps the member '.30 back to its normal position. This action moves the forwardmost ;pellet upwardly into the barrel 1, ljust forward of the barrel Further retracti ng movementcausesthebight portion A43 ofv the wire to ride upwardly in the inclined portion of the slot and into the upper horizontal portion fully urges .it mto the barrel 13, as shown by the dotted lines. The pump handle 4 is now pushed forwardly to its rnormal position and in sodoing, the bight portion 43 must pass the member 30 which lies in its way. This is permitted because the member 30, by being engaged by the portion 43, moves downwardly due to the elongated slots moving down, as regards the fulcrum pin 35. In this movement, the'member 30 fulcrums on the ears 33 and when the portion 43 clears the member 30, the same is urged back into its normal position by the spring. In other words, the spring 36 functions to permit the member 30 to be flexed downwardly at either end.

it will become apparent that the cocking of the gun, or in other words, the engagement of end 12 of the rod behind the sear 14 of the trigger must be accomplished at the time the `pellet is fed into the end-of' the barrel 13, in

order to effect perfect operation of the gun. f r

The safety mechanism now to be described,

is arranged, to positively effect both the cooking and the feeding of the pellet in a given stroke or movement of the cooking handle 4.

vBy reference first to Fig. 9, there will he seen a member which contacts directly with the trigger. This member has a pair of relparts with a cross abutment 51.- The ends of the parts 50 are pivoted as at 52-to an actuating member 53 which may be of U-shaped sheet met-al having a bight'portion 54. The member 53 is mounted in the gun upon aipivot 55. Y

`Secured in an operative manner to the reciprocating handle is a member for cooperation with the pivoted actuating member 53.

vThis member is referenced and may be of Vvchannel formation and apertured to permit the member 16 to pass therethrough (Fig. 5),

"and secured to the member 16 by a suitable pin 61. This channel extends rearwardly and just forward of the actutively large aperture 66 and a similar rela-l tively large aperture 67.- l

4In considering the action of this mechanism, turning rst to Fig. 2, where the parts are shown in normally uncooked position. The pawl 62 extends downwardly through the aperture 67. VThe operator now grasps pump handle and retracts the saine, and after some retracting movement, the parts take the position substantially as shown in Fig. 3. Note the pawl 62 catches in the small aperture 65 in a manner as to prevent a reverse movement. Should the operator now rel-ease the pump handle, the parts do not return to the normal position, but remain held by the pawl. Continued retraction of the pump handle brings the parts to the position shown in Fig. 4, where the hook 12 catches behind the sear 14 on the trigger to cock the gun. At this time the bight portion 43 of the feeding wire has pushed a pellet into the end of the barrel 13.

The next move is to return the pump handle by a forward push to its normal position. It will now be noted that the pawl 62 under the actionof its controlling spring 64, eX- tends through the aperture 66 so that it is in its normal vertical position. The handle can now be pushed forwardly and the pawl will snap along in the apertures 65 in a position just reverse to that shown in Fig. 3, preventing, however, any return movement until the pump handle has been pushed to its forwardmost position in order to allow the pawl to again assume the position shown in Fig. 2. Accordingly, this pawi works as a check both in the retracting of the pump handle and in the forward return movement of the pump handle, and insures that both the retracting movement and the forward return movement be a full and complete stroke.

In addition to this check action performed by the pawl, the trigger is locked from movement in all positions of the pump handle, ei;- cept in its forward normal position. Turning again to Fig. 2 where the parts are in normal position, it will be noted that upon retracting the pump handle the member 60 engages the bight portion 54 of the actuatiner member 53 and swings it upon its pivotalv mounting to the position shown in Fig. 3.

i This draws the members 50 forward so that the part 51 abuts up against the trigger, as

shown in Fig. 3, so that the trigger cannot be pulled. The trigger is thus held locked at the time of'cocking (Fig. 4), and remains so held until theV pump handle is returned to its normal position, thus causing the member to move `out from under the actuating member 53. The frame of the gun may be provided with an aperture 70 to afford clearance for the end of the actuating member 53 when it is cocked to the position shown in Fig. 2. The gun mayinow be fired by a pull upon the trigger, which movement may also retract the member 50 and rock the actuating member 53 from the position as shown in Fig. 4 to that shown in Fig. 2.

It will be understood that inasmuch as the trigger is heldv from movement, some movement must be provided in order to get the hook 12d over the sear 14, and for this purposel the trigger 3 and the sear 14 are made separate (Fig. 11). The trigger may be of bifurcated construction with the sear disposed therein, and the pin 3a upon which the trigger is fulcrumed may also fulcrum the sear on the trigger. A spring 175 normally holds the sear in the position shown in Fig. 11, up against a stop pin 3b, and as the hook l2 strikes the sear, the sear is cammed down thereby, as illustrated by the dotted lines of Fig. 11, against the action of the spring 15 However, as the trigger 3 is pulled by the finger of the operator, the sear 14 reciprocates therewith due to the abutment pin 3b.
